6 Claims.

. r 1 This invention relates to an abrading machine in which the abrading wheels are angularly and linearly adjustable with respect to the work.

One object of this invention is to provide an abrading machine. that has one or more abrad-.. ing wheels positioned adjustably with respect to the work.

Another object is to provide, an abrading ma-i chine in which the abrading wheels are positioned adjustably with respect to the work and in which the work support is positioned adjustably with respect tothe tableon which it, is mounted.

Further objects and advantages of this invention, as well-as its construction, arrangement and operation, will be apparent from the following. description and claims in connection with the accompanying drawings, in which Fig.1 is a top plan view of the assembled abrading machine, the motors being omitted for clarity; I p t M Fig. 2 is a front view of the assembled machine; Fig. 3 is a vertical section taken on theline 33 of Fig 1'; I

Fig. 4 is a top plan view of the motor stand; Fig. 5 is a vertical section on the line 5-5 of Fig. 4, showing parts related to the motor stand;

Fig. 6 is a side view of the motor stand, showing parts related thereto partly in section;

Fig. 7 is a top plan view oi the work support;

Fig. 8 is a frontview or the work support;

Fig.9 is a side view of the work support;

Fig. 10 is a top plan view of a modification of the work support;

Fig. 11 is afront view of the lead screw and related parts, some elements being shown in section for clarity of illustration;

Fig. 12 is a top plan view of the table; and

Fig. 13 is an end view of the table.

Similar numerals refer to similar parts throughout the several views. Figs. 1, 2, and 3 show the assembled abrading machine comprising portions designated generally as follows: a supporting table I0, motor stands 50 slidable on supporting table l0, motors I adjustable angularly on motor stands 50, abrading wheels 80, and work support I20.

The supporting table It consists of legs ll, joined together by transverse supporting members l2, welded or otherwise aflixed to the legs Shoes M are welded or otherwise afllxed to legs II. Table top I is aflixed to and above legs H as by welding. or other means. Apron l6 depends from table top l5 and is welded or otherwise fixed to it.

Lead screws 3!) are mounted in and extend be-. tween bushings34,which arelocated in brackets 22-43, and lead screw-bushing 3|, which .is mounted in work-support rail 80. Collars 32 on lead screws 3|) abutv against brackets 22-'-23.

Journalportions 3310f lead screws 30. are sup, ported in bushings-34 in brackets 22-23, while end journal portions'35 are received in leadscrew. bushing v3|.. It is to be noted that lead-; screw bushing 3| is received by a drive fit in bore.

92 of work-support rail 9!);

Sections-36 of lead-screws have keyways. 31.

for the reception of. keys .38, which are also received in keyways 39 of knurled hand-wheels 40..

Handwheels 40 are held in assembled position by nuts-4| threaded onend portions of leadscrews 3!]. Hand wheels 40 have. handles 43 threaded therein for convenience of operation.

Threaded on lead-screws 30 are lead-screw nuts 44, having endportions 45 received in bores 5| of motor stands 5|] andheld therein by means".

of retainingbolts 52 passing through bores 5| in motor stands .50.

Motor stands comprise .foundation mem-.

bers 53 having slide members 54 complementary to rails 25. i 7

Between the outer rail 25 and slides 54 of motor stands 5|l'arelocated gibs 55; Gibs 55 are connected to slide members 54 by means of gib' bosses 64. and channels of an inverted T-shape in cross section. 'Withinchannels 65 are located,-

Work-support rail is recessed at 9|. to permit'passage .ofcne of the,

Uprights 6| are connected to.

T-bolts 66, which are placed in channels 65 by insertion in hole 81. V

Motors Ill having motor base-plates II are placed on motor swivel-bases 62, bushings 6B which encompass the bosses 64 being received in recesses 12 of, motor base-plates 1,1; T'-bO1t'S 6B? are received by-bores-ilit of motor bBiSBrPlfitBS Hz and fasten motors to motor swivel-bases 62 by means of nuts 14.

4 said channels being of an inverted T-shape in cross section, an enlarged aperture in each of said channels, bolts in said channels, the heads of said bolts being located in the lower portions of said channels, the shanks of said bolts extending through the vertical portions of? said". channels, motors having apertured base-plates on said motor stands, said bolt shanks extendin through said motor base-plate apertures, fasten- Motor swivel-bases 62 are calibrated in, degrees; 10, ing. devices on said bolt shanks to secure said moat 69, indicators being inscribed on motor base-plates H to denote the angular positionof the motors in and abrading wheels 80;. Thus; .the T-shaped channels 65 and T-bolts 66 provide a construction adapted to accommodate-a widevariety of motors.

Work-support rail 90 has a groove of triangular cross-section at 93 and a channetoi" ti-slia-ped' cross-section at 94, both the groove 93 and channel 94 extending the length of work support rail 90'; Overlying the-top of rail; aflis 9;, U-shaped' slide-housingv I00 attached: adjustably-to rail an; by means of" gib Hi1! and; gib; screws m2: Nuts: L06 regulate the depth of penetration; of g rb; screws I02.
